ILLINOIS, ASSIG-NOR TO UNION SPECIAL SEAM FOR SEWED ARTICLES Applicationfiled April 8,

The invention relates to new and useful improvements in seams for sewedarticles, and more particularly to a flat covering seam for joining theedge portions of fabric sections.

[in object of the invention is to. provide a seam of the above characterwherein the fabric sections are joined by interlocked thread loopspassin through the edge portions while placed face to face, andalternately anchored in the alternate fabric sections at points backfrom the edge portions.

A further object of the invention is to provide a seam for sewedarticles of the above character wherein the thread loops are anchored bypassing into and out of the respective fabric sections on the same facethereof.

11 still further object of the invention is to provide a scam of theabove character wherein the covering thread extends across the edges ofthe fabric sections covering the same, and is secured by the interlockedthread loops at their blind stitch connection with the fabric sections.

In the drawings which show by way of illustration one embodiment of theinvention- Figure 1 is a plan view on a very much enlarged scale showingthe improved seam, and showing in section the shaping of the fabricsections;

Fig. 2 is a plan view of the threads as they are arranged andinterlocked in the finished article, and

Fig. 3 is a sectional view showing the manner of passing the needlesthrough the fabric sections in the form of the seam.

The invention is directed to a flat covering scam for joining fabricsections. The two fabric sections have their edge portions placed faceto face. The seam is preferably formed of three threads; two needlethreads and a cross thread. The needle threads are formed into threadloops; The thread loops of one of the needles is first passed into andout of one fabric section only, back from the edge thereof, thus makinga blind stitch connection therewith, and then through the edge portionsof both fabric sections. A loop in ric sections.

the other needle thread is then passed into and out of the other fabricsection only, back from the edge portion thereof, thus making a blindstitch connection therewith, and then through the needle loop of thefirst needle P and through the edge portions of the fabric sections. Thefollowing stitches are like the first two described. The loop in theneedle thread always passes into and out of the fabric section, thenthrough the loop of the edge portions a and Z) are placed face to face.Y

The threads for joining the fabric sections and making the flat seam areshown in Fig. 2. These threads consist of a needle thread 1,

a needle thread 2 and a cross thread 3. The

needle thread 1 is formed into needle thread loops 4, 4 and the needlethread 2 is formed into needle thread loops 5, 5. The needle thread 1 iscarried by a needle 6. The needle passes the loop 4 into and out of thefabric section A at the crimped portion a therein. The needle thenpasses through the edge portions of the two fabric sections. The needlethread 2 is carried by a needle 7. This needle 7 first passes throughthe crimped portion (Z of the fabric section B, and thence through theneedle thread loop 4, and then through the edge portions (1 and b of thefabric sections. On the first reciprocation of the needle 6, it willpass through the needle thread loop 5 where it emerges from the fabricsection and before it passes the edge portions of the fab- The crossthread 3 is laid about the shank of the needle loop 4 where the needleloop 4 enters the fabric section A. The cross thread then extends overthe edges of the fabric sections and about the shank of the needle loop5 where it enters the fabric secon 13.

From the above it will be apparent that the needle thread loops all lieat the outer faces of the edge portions a and b. lVhen a lateral strainis placed on the scam, the anchored portions of the needle thread 1pulling on the thread loops Will draw the edge portions of the fabricsections into closer contact. The needle thread loops 5 anchored in theother fabric section aid in drawing the edge portions of the fabricsections into close contact.

The seam is very elastic, very simple in construction, and the edges areWell covered.

It is obvious that minor changes in the details of construction may bemade Without departing from the spirit of the invention as set forth inthe appended claims.

Having thus described the invention, What I claim as neW and desire tosecure by Letters Patent, is

1. A seam for sewed articles comprising fabric sections having the edgeportions thereof placed face to face, a needle thread having a seriesofthread loops, each of which passes into and out of one fabric sectiononly and through the edge portions of the fabric sections, a secondneedle thread having a series of loops therein, each of Which passesinto and out of the outer fabric section back from the edge portionsthereof, and then through the edge portions, the loops in the needlethreads being secured by the shank of a succeeding loop, and a crossthread passing about the shanks of the successive loops in both threadsand crossing and covering the edges of the fabric sections.

2. A seam for sewed articles comprising fabric sections having the edgeportions thereof turned out of the plane of the fabric sections andplaced face. to face, series of thread loops associated With andanchored in each of said fabric sections, the loops of each of saidseries passing through the edge portions of both fabric sections andbeing locked by the loops of the other series.

3. A seam for sewed articles comprising fabric sections having the edgeportions thereof placed face to face, a needle thread hav ing a seriesof thread loops each of which passes into and out of one fabric sectiononly and also penetrates the edge portions of the fabric sections, asecond needle thread having a series of thread loops therein each ofWhich passes into and out of the other fabric section only and alsopenetrates the edge portions of the fabric sections, the loops in theneedle threads of one series being secured by the shanks of the loops inthe other series.

In testimony whereof, I affix my signature.
